• Distant scanningDistant-scanning crowds for potential threats

    Everyone wants to be safe and secure, but can you imagine if you had to go through a security screening at the metro station like there is at the airport? What if there were a way to safely scan crowds for potential threat items in places like metro and train stations without security officials coming into direct contact with the public and while maintaining individual privacy?

  • CybersecurityThreat identification tool addresses cybersecurity in self-driving cars

    Instead of taking you home from work, your self-driving car delivers you to a desolate road, where it pulls off on the shoulder and stops. You call your vehicle to pick you up from a store and instead you get a text message: Send $100 worth of Bitcoin to this account and it’ll be right over. You buckle your seatbelt and set your destination to a doctor’s appointment, but your car won’t leave your driveway because it senses it’s been hacked. These three hypothetical scenarios illustrate the breadth of the cybersecurity challenges that must be overcome before autonomous and connected vehicles can be widely adopted. While every new generation of auto tech brings new security risks, the vulnerabilities that come along with advanced mobility are both unprecedented and under-studied, the paper states.

  • Transportation securityAI used to limit collision-prone roadways

    Could a traffic agency identify a potentially dangerous road intersection without first witnessing a collision? Researchers are attempting to answer that question as they near completion on a two-year proof-of-concept study to develop an image-based system for monitoring and assessing the safety of intersections.

  • Explosives detectionHomemade Explosive Characterization Program helps keep Americans safe

    Each day almost two million Americans travel on commercial aviation domestically and internationally, and in addition tens of millions use America’s mass transit systems. In recent months, several significant plots to take down commercial aircraft and attack public spaces have been thwarted due to the mitigation efforts of law enforcement and government counter terrorism agencies across the globe. The Department of Homeland Security Science and Technology Directorate (S&T) says it is at the forefront of the response to, and mitigation against, such plots against the homeland.

  • DetectionChemical detection sensors at the new World Trade Center Transportation Hub

    In New York, a new magnificent architectural wonder in white, the World Trade Center Transportation Hub, also known as the Oculus, attracts tens of thousands of commuters and visitors every day. The Hub connects two subway systems and provides access to multiple buildings that make up the World Trade Center. However, even the most beautiful and useful places are not immune to danger from terrorist chemical attacks. DHS S&T entered into an agreement this spring with the Port Authority of New York and New Jersey to begin the design, establishment, operation, and maintenance of a chemical detection testbed for identifying hazardous gases.

  • Rail safetyConcerns about safety of rail transport of energy liquids, gases

    The U.S. increased production of crude oil, natural gas, and corn-based ethanol created unforeseen demands and safety challenges on their long-distance transportation via pipelines, tank barges, and railroad tank cars. A debate is underway about whether the domestic energy revolution was placing stress on the transportation system that would sacrifice safety.  

  • Rail safetyAverting disaster on railroad crossings

    The damsel in distress, tied up and left on the railroad tracks, is one of the oldest and most clichéd cinema tropes. This clichéd crime has connections to real, contemporary accidents that happen far more than they should. There are 200,000 crossings in the United States, and efforts to minimize the number of these crossings by creating overpasses, or elevating roadways are cost-prohibitive. Researchers found a better solution to reduce the number of accidents at railroad crossings: The Ghost Train Generator.

  • TransportationSoft target, hard problem: Keeping surface transportation secure

    Maintaining security on the U.S. surface transportation systems takes significant resources and manpower, both which tend to be in short supply. What if there were a way to detect potential threats in bags or on persons from the moment they entered the subway? What if there was a way to know the path individuals take as they move through the system, and to relay that information to transit police in real-time?

  • AnthraxCleaning up subways after release of biological warfare agent such as anthrax

    If you’re like most people, you don’t spend much time thinking about what would happen if anthrax was released into your local subway system. But Sandia Lab engineer Mark Tucker has spent much of the past twenty years thinking about incidents involving chemical or biological warfare agents, and the best ways to clean them up. Tucker’s current project focuses on cleaning up a subway system after the release of a biological warfare agent such as anthrax.

  • TerrorismU.K. raises terror threat level after London terrorist attack

    British police is searching for those responsible for an IED explosion on a London subway train. Twenty-nine people were injured in the attack. Counterterrorism experts said the IED may have malfunctioned, thus averting a larger catastrophe. British prime minister Theresa May raised the country’s terror threat level to critical, meaning an attack is expected soon.

  • Climate & transportationKeeping the trains running on time in the face of climate change

    There are many railway bridges around the world. In the United Kingdom alone there are more than 40,000 railway bridges. Each nation has employed its own methodology for maintenance and repairs of this essential infrastructure, but new, daunting challenges created by climate change — extreme heat, extreme cold, and severe flooding — require yet more rigorous solutions.

  • Car cybersecurityProtecting auto computer systems from hacks

    When you and your family are zooming along the freeway, the last thing you’re worried about is the security of your car’s computer systems. That’s one reason researchers work hard on protecting vehicles from cyberattacks. Computer engineering research team is focused on the security of wireless interfaces utilized by vehicles, the number of which will only grow as autonomous cars and trucks roll closer to reality. These interfaces in our vehicles, not unlike the computers in our homes and in our hands, can be susceptible to attacks, also known as hacks. The major difference is that attacks on a vehicle’s computer systems, which are connected to critical controls, can have potentially fatal consequences.

  • Autonomous vehicle cybersecurityPreventing autonomous vehicles from being hacked

    Although autonomous vehicles are essentially large computers on wheels, securing them is not the same as securing a communication network that connects desktop computers and smartphones to large geographical areas due to the roles that the sensors and actuators play in the physical layer of the network. Researchers have developed an intelligent transportation system prototype designed to avoid collisions and prevent hacking of autonomous vehicles.

  • Facial recognitionGermany testing face-recognition software to help police spot terrorists

    Germany will be testing facial recognition software at a Berlin train station this summer to see whether it can assist police identify terror suspects more quickly. Volunteers will help police test the software at Berlin’s Suedkreuz station. If the test is successful, the use of the biometric software would be expanded to other locations, and also used to help police identify criminals, not only people suspected of terrorist activities.

  • Flying carsUber picks Dallas, Fort Worth as test cities for flying vehicle network

    By Brandon Formby

    Uber is looking to North Texas as a testing ground for its initiative to make intra-urban flying vehicle rides a reality. The company announced Tuesday that Dallas and Fort Worth are its first U.S. partner cities for what its dubbing the “Uber Elevate Network.” The company hopes to have the first demonstration of how such a network of flying, hailed vehicles would work in three years. The company also tapped a Dallas real estate development firm and Fort Worth’s Bell Helicopter to develop pick-up and drop-off sites for electric vehicles that would take-off and land vertically.
